Indeed, the credits don't even run until after a full sex scene—Regan Reese as the pornstar Alexi blowing a stunned and confused Gilligan (played by Anthony Rosano)—has already run its course. And the rest of the movie pretty much follows in this vein.

"This Ain't Gillgan's Island XXX" is not so much a pornified "Gilligan's Island" as the characters of "Gilligan's Island" haphazardly dropped into a porn movie (a more fitting title might have been "Gilligan's Island Meets Porn Valley."). To the extent that there's a plot, it's mostly about the porn crew tricking the unwitting island inhabitants into becoming the stars of their film.

Indeed, it's not until the fifth sex scene that we even see two characters from the show in flagrante delicto—the first four scenes feature Gilligan, Mary Ann, Ginger, and the Professor being seduced in quick succession by pornstars; and then, the first sex scene which doesn't involve a pornstar is, oddly, the Skipper and Mrs. Howell, a combination that really just confused us.

Things do pick up after that, with a threeway scene featuring Ginger, Mary Ann, and Gilligan, but then, alas, it's all over, with a rather unsatisfying, slapdash ending.

Then again, these complaints only matter if you're actually looking for a porn that's somehow true to the story of "Gilligan's Island"—if you're a loyalist who'd desperately like to see an erotic reimagining of the tale of the passengers and crew of the S.S. Minnow.

If, on the other hand, you're more interested in watching hot sex scenes featuring the likes of Regan Reese, Sindee Jennings, Ryder Skye, Daryl Hanah, Anthony Rosano, Evan Stone, Jack Lawrence, Tom Fontana, and Voodoo, well, get ready to fastforward through the minimal plot and enjoy.

In dealing with the fact that she may be married to a sex criminal, Jessica's character does what any of us would do when faced with a similar prospect: she plunges herself into the seedy underbelly of lingerie modeling instead of informing her superiors of her suspicions. And you won’t believe what happens next! (Well, if you guessed that she fucks a bunch of people, we think you're pretty close. In fact, you might just be psychic.)

"Public Service" also stars Dana DeArmond, Lindsey Meadows, Daryl Hanah, and Kelly Skyline.
